this time Huawei comes with the NM-card

NM-card

After Samsung introduced the UFS-card in early 2017, this time Huawei is coming with the NM-card. This is probably a μSD card in the new "nano" form factor. This corresponds exactly to a nano-SIM with two additional contacts. After all, this card is also really to buy. But a currently price about twice for the same capacity in comparison to the μSD is already "high-spirited".
Once again it remains to be seen whether this card can establish itself or whether it will be quiet again after some time, as with the Samsung UFS card...

new port of the RTOS kernel pC/OS

powerPC

The pC/OS Kernel was ported to the powerPC e200z4 with Lockstep-core MPC5744P from NXP/Freescale. As toolchain the NXP S32 DesignStudio IDE was used.

new port of the RTOS kernel pC/OS

Cortex-M

The pC/OS Kernel was ported to the Microchip/Atmel Cortex-M7 SAMS70. As toolchain the ARM/Keil MDK was used.

new version of the RTOS kernel pC/OS

A 'dynamic modi' for Pipes was added to the pC/OS kernel. The IPC 'Pipe' now can use the memory manager internally as message storage instead of the fix created (size) array, but warning - it requires additional time and can result in some side-effects.

new port of the RTOS kernel pC/OS

Cortex-M23

The pC/OS Kernel was ported to the GigaDevice Cortex-M23 GD32E230. As toolchain the ARM/Keil MDK and the IAR Embedded-Workbench were used.

And sorry to Renesas, I have a TB-S1JA boardTB-S1JA Board, but I'm not going to get caught up in magical Renesas tools/libraries (SSC/SSP plus redistribution rules) - this is a Cortex-M23 w/o TEE - so a Cortex-M0+ successor and not a "special processor".

revised porting of the RTOS Kernel pC/OS and the pC/SFS (small) Serial File System

Cortex-M23

The porting of the pC/OS Kernel and the pC/SFS (small) Serial File System on the Cortex-M23 Nuvoton M2351 has been redesigned. With help from Nuvoton-Support, I was able to revive my NuMaker PFM-M2351 board and track the problems of porting the pC/SFS up to the "partition_M2351.h" and finally complete the port of pC/SFS (small) Serial File System for SPI and I2C.
